JupyterLab: How to save a figure from the notebook

Following the suggestion from @Matt, I opened an issue in GitHub and got the answer: the old menu is available by holding down Shift while doing a two-fingers click on a Mac, or doing a Shift + right-click on Linux/windows

Shift + Right click works well (as foglerit mentioned).

Another alternative is to right on the output of a cell and select Create New View for Output. This will allow you to interact with all figures from an output as if they were just images.
